LINEMANS CHAIR Application led December 12, 1927.

relates to improvements in and has for its primary object a linemanschair, the wheels of which are provided with a resilient center portionor easily negotiate or ride over cable hangers, clamps and thiniblesbecause the tread being resilient can compress when riding over theseobstructions and consequently the lineman in the chair is not jarred asis the case'where wooden or metal wheels are used.

A further obj eet is to construct a linemans chair, the yoke of which isso arranged that in the event ot the chair being tilted and the wheelssliding od of the wire, the yoke wi hook on to the wire and prevent thechair from falling to the ground. By this construction, the possibilityof injuring persons passing along underneath the Wire is eliminated.

In the drawings:

Fig. 1 is a side elevation of my device;

Fig. 2 is an end view of the saine;

Fig. 3 is an enlarged vertical cross section of one of the wheelsshowing the manner of assembling the same; and

Fig. 4 is a Jiragmental cross section of a wheel showing a differenttype of tread.

In the construction of my device I einploy a yoke 5, which is providedwith downwardly and outwardly diverging arms 6 and 7. The arm 7terminates in a hook 8, which projects upwardly and inwardly. The arm 7is also provided with a downwardly extending guide or guard 9.

Carried by the arm 6 is a stirrup or bracket 10 to which the seat board11 is secured. In order to couple two yokes together, I employl a crossrod or bar 12, which has its ends 13 secured to the yokes. The yokes areurther secured to the bar 12 by means of brackets 14, one of thesebrackets being on each side of each wheel. This prevents any possibilityof the yokes moving backward and forward on the bar 12.

The wheel is composed of side members 15 and 16. These side members havetheir inner face grooved or channeled out as indicated by the numeral 17so as to form a shoulder 18.

Formed integral with the members 15 and 16 and projecting from the innerfaces there- My invention linemans chairs,
